It's About Time... Traffic Signal Management: Cost Effective Street Capacity and Safety
This video demonstrates the benefits of maintaining current, optimized and coordinated traffic signal timing plans, and investing resources in traffic signal systems. The video explains how to use existing traffic signal equipment already in place, combined with available tools, techniques, and in some cases improved equipment, to more efficiently utilize city streets and signal systems. Examples document reduced travel time, delay and fuel consumption with very high benefit to cost ratios. The video describes the types and uses of signal systems, techniques used to optimize the signal system, and how to implement and monitor signal timing plans, including staffing and cost issues. If signals are correctly managed, benefits can include: reduced emissions, fuel consumption, traffic congestion, aggressive driving behavior, and severe accidents; postponed or eliminated construction of additional capacity; and time savings for commercial and emergency vehicles, buses and the public.
